If your processor is capable of utilizing the DDR Ed it won't really matter how much SDRAM you stuff in the slots. It isn't a question of the amount of memory in place so much as a question of how it operates. The processor (Athlons, Durons) is able to access the data faster from DDR because data is read on every 'clock cycle'. "Rising and falling rather than rising only."
That said; an article some time back on AnandTech showed only roughly 3 to 7 per cent speed increase in benchmarks. If you are using an older processor that isn't optimized for it you won't notice a difference anyway. AFAIK anything less than ~10% isn't detectable without instrumentation. I'd still go DDR but I'd wait for "333MHz" rather than using what is available now. The price is at somewhat of a premium right now as well.

I would also expect the differnce between 64 meg DDR and 90 megs sdr sdram to be about the same, depending on the application On Friday 15 March 2002 18:01, you wrote: > No question but that DDR is the better solution for any 'performance box.' > Think it through; DDR = Dual Data Rate.
